Long-term effects of the Meniett device in Ménière's disease: the Western Australian experience

OBJECTIVES: Transtympanic pressure has been shown to influence endolymphatic hydrops. As endolymphatic hydrops plays a key role in Ménière's disease, a few studies, undertaken by the inventors, manufacturers and associates of the Meniett device, have demonstrated positive short-term effects of transtympanic pressure treatment via the Meniett device in medically intractable Ménière's disease. The aim of our study was to independently investigate the long-term efficacy and safety of transtympanic pressure treatment in the management of recalcitrant vertigo in Ménière's disease. DESIGN: Cross-sectional case study. SETTING: Tertiary referral centre. PARTICIPANTS: Eighteen patients with Ménière's disease, suffering from medically intractable symptoms. All patients in the study had Ménière's disease according to the criteria of the Committee on Hearing and Equilibrium of the American Academy of Otolaryngology, Head & Neck Surgery.Main outcome measurements: Outcome and severity of symptoms were assessed, using the six-point functional scale and the vertigo visual analogue scale (VAS), as recommended by the Committee on Hearing and Equilibrium of the American Academy of Otolaryngology, Head & Neck Surgery. Changes of pure tone average thresholds and vestibular calorics before and during treatment with the Meniett device were recorded. The mean follow-up time was 18 months. RESULTS: Twelve out of 18 patients showed significant improvement in the functional score and in the VAS. Five patients displayed an audiometric improvement, out of which three patients showed a pertaining significant hearing gain of more than 10 dB; the remainder had stable hearing levels. Of six patients without any improvement, four had previous invasive surgery for their Ménière's disease and two had previous vestibular ablation with gentamicin. No changes in vestibular function were noted. There were no complications during the treatment with the Meniett device. CONCLUSION: According to this independent study, the Meniett device seems to be a minimally invasive, non-destructive treatment tool, which can reduce vertigo and associated functional handicap in Ménière's disease. These effects are maintained up to 18 months after treatment so far. Previous surgical or chemical vestibular ablation procedures may adversely influence the effect of the Meniett device.     

Clinical long-term effects of surgical treatment for intractable Meniere’s disease: a more than 13-year follow-up after pressure treatment and further surgical treatment for intractable vertigo

Abstract

Background: Meniere’s disease appears to be a complex inner ear disorder and also remains a controversial and often difficult disease as regards determination of diagnosis, pathogenesis and especially optimal treatment.

Aims/objectives: To investigate the long-term effects of progressive surgical treatment in the management of the vertigo attacks of intractable Meniere’s disease.

Material and methods: Eighteen patients with medically intractable and active Meniere’s disease were opted to try Meniett pulse generator (Meniett), endolymphatic sac decompression (ESD) and triple semicircular canal occlusion (TSCO) in order to control the attacks of vertigo. Patients were indicated on the symptom report card the maximum level of vertigo, activity and stress.

Results: Of 18 patients with medically intractable and active Meniere’s disease during mean 165-month follow-up, the attacks of vertigo were effectively controlled in 14 patients by Meniett (77.78%), 2 patients by Meniett and ESD (11.11%), 2 patients by Meniett, ESD and TSCO (11.11%).

Conclusions and significance: It is of great importance for intractable Meniere’s disease to select surgically combined treatment process including Meniett, ESD and TSCO to effectively control the attacks of vertigo and a long-term follow-up.     

乙状窦后进路内镜下前庭神经及部分耳蜗神经切断术治疗梅尼埃病

Indikation und Erfolge der operativen Therapie des vestibulären Schwindels

The indications for surgical treatment of labyrinthine vertigo associated with severe impairment and a lack of response to medication are heterogeneous. Due to different therapeutic goals and success parameters, the results of treatments can only be compared to a limited extent. This overview of the current literature and procedures performed by the author contains recommendations for indications and outlines the risks associated with operative therapy of vestibular vertigo. Results of function-preserving and ablative therapies are compared. Surgical treatment of Menière’s syndrome (non-idiopathic) using tympanostomy tubes is indicated in cases of increased middle ear pressure; Meniere’s disease (idiopathic) in its early stages can be treated with the endolymphatic shunt operation to preserve hearing and balance functions and where these techniques fail, with vestibular neurectomy for preservation of hearing or with cochleosacculotomy in the case of deafness. Rare indications are intractable benign paroxysmal positional vertigo and superior semicircular canal dehiscence syndrome (SCDS). The function preservation success rate in cases of Meniere’s syndrome and disease is 70–88?%, ablative procedures are effective in >?90?% of cases and occlusion of the superior or posterior canals is successful in >?95?% of patients.     

Meniett therapy: rescue treatment in severe drug-resistant Ménière's disease?

CONCLUSION: Our data indicate that Meniett therapy is unlikely to be helpful in the long-term treatment of patients with severe, drug-resistant Ménière's disease (MD) in whom injection of intratympanic gentamicin (ITG) or another destructive procedure would otherwise be performed. OBJECTIVE: To investigate the value of Meniett therapy in patients with drug-resistant MD referred for injection of ITG. MATERIAL AND METHODS: Twelve patients referred for ITG treatment were followed during a 2-month period of Meniett therapy. Symptoms, functional level and hearing status were evaluated using a standardized staging system. Disease-specific quality-of-life measures were obtained before and after Meniett therapy. At the end of the study period, patients were followed for a mean of 37 months, thus providing long-term outcome data. RESULTS: In two patients, Meniett treatment was interrupted after 1 month because of persistent severe vertigo. In the remaining 10 subjects, we found a significant decrease in the median number of vertigo spells from 10.0/month (25th-75th percentile 4.0-19.0) prior to treatment to 3.0/month (25th-75th percentile 1.5-4.5) after treatment (p = 0.02). There was, however, no improvement in hearing status, tinnitus, functional level or self-perceived dizziness handicap. Long-term (>1 year) follow-up data revealed that only 2 subjects preferred to continue Meniett therapy and that ablative surgery had to be performed in 6/12 study patients.
